- Add language field to balance topup and landing purchase requests
- Cap news article featured image height with max-h-96
Cherry-picked from PR #362 (without favicon change — files don't exist)
- Balance page: handle select_subscription response — show subscription
picker when promo code adds days and user has multiple tariffs
- API: activatePromocode now accepts optional subscriptionId
- AdminPromocodeCreate: show trial tariff info when creating
trial_subscription promo code, warn if no trial tariff configured
When payment providers redirect to external browser, sessionStorage is
unavailable. TopUpResult now reads method from URL query params and
polls via /latest endpoint as fallback.
Replace toast-based payment return with animated result page showing
pending/success/failed/timeout states. Extract shared Spinner,
AnimatedCheckmark and AnimatedCrossmark components. Add sessionStorage
persistence with validation and TTL for cross-redirect payment data.
Unify ProtectedRoute with withLayout prop, add aria-live accessibility.
